Advertisements Recently took the offer for a new Tivo Bolt with transfer of a lifetime service program. The new Tivo Bolt has many wonderful features, it takes up far less space, and has 4 tuners! However, a major difference from Series 2 was essentially ignored in the promo. Series 2 allowed user to choose quality as Basic, Medium, or High, a range of factor 6x in regards to use of memory storage. BOLT has a sleazy option choice between high def, OR NOT. In many case, choosing "not high def" means that shows will not record at all. Bottom line, even upgrading to a 2TB hard drive might let you program about 500 hrs with this quality, far less than the anticipated 2700 hrs expected if we had the same options of control of quality as before.
